FEATURES
DESCRIPTION
The DS1023 is an 8-bit programmable delay line similar in function to the DS1020/DS1021.
Additional features have been added to extend the range of applications:
The internal delay line architecture has been revised to allow clock signals to be delayed by up to a full
period or more. Combined with an on-chip reference delay (to offset the inherent or “step zero” delay of
the device) clock phase can now be varied over the full 0-360 degree range.
Step sizes of 0.25 ns, 0.5 ns, 1 ns, 2 ns, 5 ns
On-chip reference delay
Configurable as delay line, pulse width
modulator, or free-running oscillator
Can delay clocks by a full period or more
Guaranteed monotonicity
Parallel or serial programming
Single 5V supply
16-pin DIP or SOIC package
